Ancient carbon

Frozen organics stick out from the walls inside the Permafrost Institute in Yakutsk. Dating back to the end of the Pleistocene, the time when the Mammoths roamed this terrain. Under warmer conditions, organic material frozen for millennia will break down and release greenhouse gases such as methane, a gas 23 times more effective at trapping solar heat than carbon. Despite it's shorter atmospheric lifespan the sudden release of vast quantities of methane would increase the greenhouse effect exacerbating climate change.
